IMPROVEMENT IN SPRING BED-BT'ONIS.

Specification describing a new Suspension Spiral-Wire Spring Bed-Bottom, invented by' SIDNEY B. ANDREWS, of thecity of Chicago, in Cook county and State of Illinois.

My invention relates to what I terni a suspension spiral-wire spring bed-bottom.

In the accompanying drawing, Figure l represents a horizontal or face view of my invention as it appears when completed and ready for use. Fi 2 represents a side elevation, and shows the position of all the parts of my invention except the rings, which appear in Fig. l. Fig. 3 represents a sin glc spiral spring with its connections when in its proper position in the invention.

My invention consists of tive different parts:

iirst, a Wooden frame; second, spiral springs 5` third, rings; fourth, hook-links, and iifth, suspension Wires.

In Fig. l, A is a wooden frame, Within which my invention is constructed and suspended. This wooden frame shouldbe made of strips ot' hard stift' wood, about three inches wide and one land onchalf inch thick. In Fig. l, b represents the spiral-wire springs in a horizontal view, and in the same figure o represents the rings as they appear in a horizontal view in their proper places; and d represents the hooklinks, by which the springs and rings are connected in Figs. l, 2, and 3. In Figs. l and 2, e represents the suspension wires, which pass around the frame A and hold the entire combination of springs, rings, and hook-links in suspension in the frame A. The suspension wires e are all held in their proper places on the frame by means ofthe small wire staples f, which are sunk into the frame A so as to include the suspension Wires between the legs or prongs ofthe staples. This is only intended to prevent the suspension wires from moving laterally on the frame, not to fasten them, as they are intended to have a free perpendicular action at right angles With the irame.

B y reference to Fig. 2 it will 'be seen that my one of the same kind.

Care must be taken, in the construction of my invention, that every part--sprin gs, rings, hook-links, and the suspension wires-shall all be tightly connected together in the frame, so

that every part may answer the purpose for- Which it is designed. This being done, every part of my invention will sustain every other part, as they are all closely connected, and any weight or pressure upon any part of it draws equally upon all the other parts.

It', in the construction of my invention, it is desirable to produce a bed-bottom which will sustain greater weight, any number of the rings may be removed and an equal number of springs put in their places; and when less stiness is desired a few of the springs may be removed and rings substituted.

Having thus described my invention, what I claim as new and as my invention, and desire to secure by Letters Patent, is

The combination ot' the several parts of my invention--viz.-, the springs b, rings c, and links d, with the suspension wire c and frame A-so as to form a suspension bed-bottom, substantially as and for the purposes set forth..
